How the date is calculated
The date is found by moving 100 days backward from today's date on the calendar, so month lengths and leap years are handled exactly. All dates use UTC, so close to midnight the date where you are can differ by one day.
Business days skip Saturdays and Sundays but not public holidays, which differ by country. For another number of days, or a start date other than today, use the date calculator or the day counter.
